Specification of Letters Patent.

Patented Dec. 28 1915.

Application filed .Tune 12, 1914;. Serial No. 844,788.

$12, a citizen of the United States, residing at East Chicago, in the county of Lake and 'tate of Indiana, have invented certain new and useful improvements in J olting-Machines, of which the following is a specification.

This invention relates to improvements in jolting and jarring machines, and as its primary object aims to provide a mechanically operated jolting machine which will efliciently jolt or ram the sand in the making of cores and molds of all kinds.

Another object of the invention is to so construct the machine that the table on which the flask or mold is placed may be raised at uniform speed and the table dropped without injury to the raising mechanism.

The above and additional objects are ac complished by such means as are illustrated in their preferred embodiment in the accompanying drawings, described in the following specification and then more particularly pointed out in the claim -which is appended hereto and forms a part of this application.

In describing my invention in detail reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a longitudinal sectional view of a jolting machine constructed in accordance with the present invention; Fig. 2 is a top plan view of the machine, the table hav ing been removed; Fig. 3 is a section on the line 3-3 of Fig. 1; and Fig. 4: is a detail perspective view of the jolting wheel.

Referring now to the drawings by numerals, l designates the frame or body of the machine, the same being box like in its nature and having an open top as shown. The jolting wheel, designated as an entirety by the numeral 2 is mounted for rotation within the frame 1, said wheel having secured thereto or formed integrally therewith a shaft or spindle 3, the axis of which extends vertically relatively to the frame; bearings 44: and 5 being provided therefor. Bearing 4- is formed at the intersection of brace arm 6, while bearing 5 is formed in the base of the frame. As a means whereby shaft 3 may be locked against vertical movement relatively to the frame, I provide an adjustable screw or pin 7 said pin operating within an annular groove (not shown) of the shaft.

The top face of jolting wheel 2 is so formed or cut as to provide a plurality of inclined surfaces 8, each surface tapering to a point 9. A. wall or shoulder 10, substantially vertical, is formed, as shown to advantage in Fig. 4, adjacent the upper terminal of each inclined surface 8, the base of the shoulder or wall 10 being at a point 11 from which the adjacent inclined surface begins to rise. A plurality of web like braces 12 radiate from the shaft or spindle 3 and brace the wheel 2.

Mounted upon the wheel 2, and reciprocable through rotation thereof, is a table or platform 13, the under surface of which carries rollers 14 disposed for engagement with the top face of the wheel, the rollers riding upon the inclined surfaces 8 thereof thus causing the platform to gradually or slowly rise and, as the rollers pass over the vertical walls 10, suddenly drop again to the inclined surfaces, adjacent the points 11. As the flasks or molds are mounted upon the table or platform 13, and held thereon by pins or uprights 15, it is apparent that the same will be jarred or jolted to in this manner provide for a ramming of the sand therein.

A flange 16 depends from the platform 18, the flange engaging the outer face of the frame 3 and serving as a means whereby the interior mechanism of the machine is protected from the sand and the like falling over the sides of the platform during a 011:- ing operation.

Guide rods 17, preferably four in number, depend from the table or platform 13, the respective rods fitting bearings 18 therefor, rigid with the frame, this arrangement as is quite apparent, holding the table or platform against rotation and guiding the same during a reciprocation or jolting operation.

Any suitable means such as a pulley 19 and driven belt 20 may be provided to impart to shaft or spindle 3 the necessary rotary movement to operation.

From the foregoing, taken in connection with the accompanying drawings it is apparent that the table or platform 13 will be jolted or jarred, by rotation of wheel 2, to in this manner efficiently ram the sand or other material used in the molds or flasks; that the rise of the platform is gradual; and

that the drop,- quite sudden, this being made possible by the arrangement of the rollers relatively to the surfaces 8 and the vertical adoption of my device will necessarily vary,

I desire to emphasize the fact that various minor changes in details of construction,

proportion and arrangement of parts may be resorted to, when required, without sacrificing any of the advantages of my invention, asdefined in the appended claim.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is

In a jolting machine, an open end boxlike casing; a relatively movable platform providing a cover therefor; a marginal fiange'formed on the platform to overhang and frictionally engage the top outside Wall of the casing; a plurality of rollers hung to depend from the under side of the platform; a casting rotatable in a horizontal plane beneath the platform, the top face of the casting being provided with fiat radial engaging surfaces, a corresponding number of vertically extending engaging surfaces, and an inclined engaging surface leading from the bottom of each vertically extending surface to the adjacent flat engaging surface for the purpose specified; the rollers aforesaid being positioned to engage the several flat surfaces simultaneously; a shaft integral with the casting; means to rotate the shaft, the shaft and the casting being removable from the casing as a unit; and means interiorly of the casing and engaging the shaft to afford a bearing support therefor.

In testimony whereof I aflix my signature in presence of two witnesses.
